University of North Carolina at Charlotte, University City Blvd, Charlotte, NC, WebAug 7, 2024 · We can use DBSCAN as an outlier detection algorithm becuase points that do not belong to any cluster get their own class: -1. The algorithm has two parameters (epsilon: length scale, and min_samples: the minimum number of samples required for a point to be a core point). Finding a good epsilon is critical. DBSCAN thus makes binary predictions ...
